MAGHI NE FOR CUTTING BUTTON-FLIES.

SPECIFICATION forming part of Letters Patent No. 462,205, dated October 2'7, 1891. Application filed March 11, 1891. Serial No. 384,525. (No model.)

The adj ustinging beyond the top and bottom of the post, screw is prevented from leaving the fixed po- I00 the upper end of which slide is provided with sition by means of an engaging set-screw 29. a journal-box 11, in which a horizontal spin- Upon the base, near the outer edge, two or more guide-standards 30 are located, and near the inner edge of the base two or more similar standards3l are placed, the stand ards 3L each being provided with a horizontal set-screw 32. An anvil-block 33 is located between the guide-standards 30 and 31 and is held rigidly in place by causing the setscrews 32 to engage therewith, as shown in Fig. 3. The anvil-block is preferably made of wood, and its upper face becomes very quickly lacerated by engagement with the cutting-tool employed to form the scallops. It is therefore necessary that the marred face should be planed down or otherwise rendered smooth, and in so doing the thickness of the block is lessened; but by employing the setscrews 32 the block maybe elevated as high as necessary and held in such elevated position by the frictional contact with the setscrews and with the guide-posts 30.

A post or standard 34 is located upon the extension A of the base, preferably at its center near the edge. This post 34 is preferably provided with a socket, in which the lower end of a pillar 35 is inserted and se cured. The upperend of the pillaris reduced, forming a shoulder 36, and upon the reduced end a horizontal arm 37 is pivoted. while upon the outer end of the arm two or more auxiliary arms 38 are pivotally attached,the outer ends of the auxiliary arms being'provided with spring-pressed cutters 39. The cutters in cross-section represent reverse concaved surfaces at their inner faces, and when employed shape practically the contour of two scallops 40 upon the fly 41, as illustrated in Fig. 4. The shanks of the cutters pass up through the ends of the auxiliary arms 38, and the shanks at their upper ends are provided with heads 42 and are surrounded by springs 43 between the heads and the upper surfaces of the arms.

One cutter only is employed during the operation of producing the scallops, and the cutters are preferably of different sizes. As two or more cutters are located upon each machine, it is necessary that the cutter not in use should be held out of the Way of the operator. This is ordinarily accomplished by screwing into the top of the pillar 35 a ferrule 44, containing'zispring-pressed verticallymovable pin 45, and the said pin is adapted to enter a recess in the under side of the auxiliary cutter-arm not needed.

In operation the flies are placed in suitable quantities, one upon the other, upon the anvilblock and against the guide-pins 26 as the said pins are brought to an engagement with the anvil-block prior to placing the flies in position and serve to define the rearward position of the flies. The treadle 16 is then pressed downward, which causes the clamping-head to engage with the flies and adjustitself thereto, and the cutter is swung .over and manipulated to produce scallops in one'edge of the flies corresponding to the scallops of apattern placed on top of the pile of flies. By producing the channel 19 in the spindle both of the fingers 26 are compelled to engage with the anvil-block at the same time, as the guide-arm cannot slip upon the spindle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with an adjustable anvil-block, a slide, and means for operating said slide, of a spindle adjustably connected with the slide, a guide-arm adjustable upon the spindle and provided with spring-pressed guide-fingers adapted for engagementwith the anvil-block, and a clamping-head adj ustable upon the spindle, as and for the purpose specified.

2. The combination, with an adjustable and removable anvilblock, a spring-controlled slide located at one side of the block, and an adjustable spindle having a bearing at one end in the slide, of a guide-arm adjustable upon the spindle and provided with springpressed guide-fingers adapted for engagement with the anvil-block, and a clamping-head also adjustable upon the spindle located over the anvil-block, the said clamping-head bein g capable of slight rotary movement, as and for the purpose specified.

The combination, with an adjustable and removable anvil-block, a spring controlled slide, and an adjustable spindle having one end inserted in the slide and provided with a longitudinal groove and an aperture near one end of the groove, of a guide-arm held to slide upon the spindle, a set-screw passing through the guide-arm into the groove of the spindle, spring-pressed fingers carried by the guide-arm and adapted for engagement with the anvil-block, a clamping-head loosely mounted upon the spindle over the anvilblock, and an adj listing-screw passed through a portion of the clamping-head into the ap erture in the spindle, as and for the purpose specified.

4. The combination, with avertical adjustable and removable anvil-block, a slide located near one side of the block, a spindle having one end supported by the slide and adjustable in the slide, a guide-arm adjustable upon the spindle, spring-pressed fingers located in the guide-arm, and a clamping-head adjustably located upon the spindle over the anvil block and capable of a compensating or slight rotary movement, of a pivoted bracket-arm located near one side of the anvil-block, auxiliary. arms pivoted upon the bracket-arm, spring-pressed cuttingtools carried by the auxiliary arms, and means, substantially as described, for locking one of the auxiliary arms, as and for the purpose set forth.
